Interview Questions on AWS Elastic
Compute Cloud (EC2)
1. What is Amazon EC2?
• Amazon Elastic Compute Cloud (Amazon EC2) is a web service that
provides secure, scalable computing capacity in the cloud.
2. What are EC2 instances?
• EC2 instances are virtual machines (VMs) that run on Amazon Web
Services infrastructure. They are the backbone of Amazon EC2 service
and provide the computing capacity for your applications.
3. What is an Amazon Machine Image (AMI)?
• An Amazon Machine Image (AMI) is a pre-configured virtual machine
image, used to create EC2 instances. It contains all the information
necessary to launch an instance, including the operating system,
application server, and any additional software required to run the
application.
4. What is an EC2 instance type?
• EC2 instance type refers to the hardware configuration of an EC2
instance. EC2 instances are available in various instance types, each with
different computing, memory, and storage capabilities.
5. What is Auto Scaling in EC2?
• Auto Scaling is a feature of Amazon EC2 that allows you to automatically
increase or decrease the number of instances based on changes in
demand for your application. This helps to ensure that your application
has the resources it needs to meet changing demands, while also
keeping costs under control.
6. What is Amazon Elastic Block Store (EBS)?
• Amazon Elastic Block Store (EBS) is a persistent block-level storage
service for use with Amazon EC2 instances. EBS volumes provide raw
block-level access to your data, which you can use to store application
data, databases, and file systems.

7. What is Amazon EC2 Security Group?
• Amazon EC2 Security Group is a virtual firewall that controls inbound
and outbound traffic to an Amazon EC2 instance. It acts as a firewall for
your instance, allowing you to control network access to your instances.
8. What is Amazon EC2 Key Pair?
• Amazon EC2 Key Pair is a secure way to log into your EC2 instances. You
use a private key to log in to an EC2 instance, and you use a public key to
encrypt your private key. The public and private key are paired, and you
cannot log in to an instance without both keys.
9. What is an Elastic IP address in EC2?
• An Elastic IP address is a static IP address designed for dynamic cloud
computing. You can associate an Elastic IP address with a running EC2
instance or a network interface, and you can control the IP address even
if you stop and start the instance or move the instance to a different
network interface.
10. What is EC2 Placement Group?
• EC2 Placement Group is a logical grouping of EC2 instances within a
single Availability Zone. Placement groups enable you to place your
instances closer together, reducing network latency and increasing
network throughput.
11. What is Amazon EC2 Spot Instances?
• Amazon EC2 Spot Instances allow you to bid on unused EC2 capacity and
run your applications at a lower cost compared to On-Demand instances.
Spot Instances are ideal for flexible, fault-tolerant applications that can
be interrupted.
12. What is EC2 Auto Recovery?
• EC2 Auto Recovery is a feature of Amazon EC2 that automatically
recovers instances that have failed due to hardware issues. EC2 Auto
Recovery automatically replaces the failed instances with healthy
instances to minimize the impact of hardware failures.
13. What is Amazon EC2 User Data?
• Amazon EC2 User Data is data that you can pass to an EC2 instance at
launch time. You can use user data to pass a script to be executed during
launch, configure the instance, or pass other data to your instances.

14. Can you explain EC2 instance store?
• EC2 instance store, also known as instance-backed storage, is a
temporary storage option for Amazon EC2 instances. Instance store
provides non-persistent storage for instances, which means that the data
stored on an instance store volume is lost when the instance is stopped
or terminated.
15. What is EC2 Dedicated Instances?
• EC2 Dedicated Instances are Amazon EC2 instances that
run on hardware that is dedicated to a single customer. These instances are
isolated from other instances and are dedicated to running your workloads,
providing you with increased security and performance compared to other
EC2 instance types.
16. What is EC2 T2 Instances?
• EC2 T2 instances are general-purpose instances that are designed to
provide a balance of compute, memory, and network resources, and are
suitable for small-to-medium sized applications. T2 instances are a good
choice for applications with low to moderate CPU usage and provide a
baseline level of CPU performance that can be burst as required by the
workload.
17. What is EC2 M5 Instances?
• EC2 M5 instances are the latest generation of general-purpose instances
in Amazon EC2. They offer a balance of compute, memory, and network
resources, and are designed for applications that demand high
performance and low latency.
18. What is EC2 R5 Instances?
• EC2 R5 instances are the latest generation of memory-optimized
instances in Amazon EC2. They are designed for memory-intensive
applications, such as high-performance databases, distributed memory
caches, in-memory analytics, and other applications that require high
levels of memory and low latency.
19. What is EC2 I3 Instances?
• EC2 I3 instances are the latest generation of storage-optimized instances
in Amazon EC2. They are designed for applications that require high,
fast, and consistent I/O performance, such as NoSQL databases, data
warehousing, and Hadoop/Spark clusters.

20. What is EC2 GPU instances?
• EC2 GPU instances are Amazon EC2 instances that are optimized for
GPU-accelerated workloads, such as machine learning, scientific
computing, and data processing. EC2 GPU instances provide access to
high-performance GPUs, making them ideal for a wide range of
compute-intensive applications.
21. What is EC2 Nitro System?
• The EC2 Nitro System is a combination of dedicated hardware and
software components that provide the underlying infrastructure for
Amazon EC2 instances. The Nitro System provides high performance
and security, and enables the delivery of new EC2 instance capabilities,
such as local storage, and higher network and storage performance.
22. What is EC2 Instance Connect?
• EC2 Instance Connect is a feature of Amazon EC2 that allows you to
securely connect to your instances using Secure Shell (SSH). EC2
Instance Connect eliminates the need to manage SSH keys, and makes it
easy to securely connect to instances.
23. What is EC2 Instance Metadata?
• EC2 Instance Metadata is data about your EC2 instances that you can
access from within the instances. Instance metadata includes
information such as the instance ID, VPC ID, subnet ID, and more. You
can access instance metadata using the EC2 metadata service.
24. What is EC2 instance lifecycle?
• The EC2 instance lifecycle consists of several stages, including launch,
run, stop, and terminate. The EC2 instance lifecycle is managed by
Amazon EC2, and you can control the lifecycle of your instances through
the EC2 console or APIs.
25. Can you explain EC2 instance Types?
• EC2 instance types are the various hardware configurations available for
EC2 instances. EC2 instance types are optimized for different workloads,
such as compute-intensive, memory-intensive, storage-intensive, and
GPU-accelerated workloads. EC2 instances are available in several
families, including T, M, R, I, G, and P, each of which is optimized for a
specific use case.
